Very good idea, and very good project.

Nice, it's a long time ticket, and sure we'll discuss that when time

You can DnD multiple files, and send them in one shot. But receiver wil
have to accept them one by one. Too bad. I haven't read Jingle FT
specifications, but is it possible to do the negociation ofr several
files? If yes that's the solution, else we'll have to discuss that in
standards mailing list, so that it's added to the XEP or a new XEP
should be written to be complient with other clients. This will take
some time to define that, so not sure you'll have time to implement that.

I already saw discussions about encrypted jingle sessions ... But I
don't know the status of that at all.

>   Any advices, thoughts, suggestions, questions are welcomed!

I have to tell you that you're not the only one contacting me for this
project. I don't know how many slots XSF will have this year, and I
don't know how many valuable project they will receive, so it's
impossible to know how many slots Gajim will have (if any).
Jingle file transfer is in XSF priorities, so this kind of project will
be in the top of the list. I think.

I could be a good idea indeed to present yourself to XSF comunity so
that people who will vote for projects know a bit about you.

Wow that's very a generous proposition!

We have some interesting propositions, see [1], and have also some
interested students. At least 2 students contacted me directly for that.
I'll see if they are still interested.

In the GC today Arc Riley asked if we wanted to get into GSoC under the
umbrella of the Python Software Foundation. He's the PSF's coordinator
this year, and says that we may be able to get a slot there (assuming
there's a decent student proposal).

Do we want this? Do we have any good project ideas?

PS. he had some great encouragement too:

extensions

I pay 35€ per month, but I also use it for my personal usage, so it's
normal I pay it.

Of course I'm not against some help, but I want to be honest, it's not
vital.

I don't know what's the server cost but I guess we could do some kind

Bad news :(

But indeed I don't plan to apply as an organisation. So no GSOC for this
year. I'll pay the server myself.

I guess this pretty much ends discussion for this year's GSoC.

Unless Gajim plans to apply as separate org, which IMHO is not a good
idea currently, keeping in mind all the program administration tasks.

+ handle thing with google (payment for example). Really I don't have

codecs are handled by gstreamer, not sure we do a lot about that. I CC
to liori who may have ideas about that.

Yep that are projects I thought about. But I don't know if it's hard and
long enough for a GSOC project (3 months full time job).As we'll already
have jingle for voice, is adding FT or video hard? I cannot answer.

I don't think such a project would be accepted by XSF members. Plugin
system last year was hardly discussed, and not easily accepted.

Not that what you said is useless, of course! But it doesn't promote
XMPP directly, showing new feature that can be done thanks to XMPP.

Esessions: already in release, and I don't see any bug.
Jingle: Liori will work on that after his exams, in some weeks.
Plugin system: I'll talk about that with Vardo. Maybe on wednesday.

But that doesn't mean someone else cannot work on a new feature. I
cannot do everything in this project: discuss and fix tickets, implement
new features. I need help. So anything that can bring help (GSOC for
example) is very welcome.
