Comments welcome. Especially from you, Blizzard, since easily
installable and transferable activities is your baby :)
You wrote: 'Each activity bundle must, in its root directory, contain

".info" rather than ".activity"'.
IMHO a fixed name, like "activity.info" would be preferable.
We could then rename the bundle, try different versions etc. without
needing to touch the inside. Also it would be simpler to script:
grep default_type *.activity/activity.info
It's common practice as well, like JAR's manifest.mf or OS/X bundle's
info.plist.
Dan,
I tend to agree with Bert reasoning here.

Currently SUGAR_PROFILE is the profile name and the actual profile path
is ~/.sugar/$SUGAR_PROFILE. We might specify this or have the session to
export SUGAR_PROFILE_PATH based on SUGAR_PROFILE.
icon = activity-web
This key is optional. It points to the activity's icon. The
icon is first searched for in the >activity bundle's root directory, and
if not found, is looked up in the current GTK icon >theme. It cannot
contain a path.
What is the actual icon filename when looking up the bundle directory?
$icon + '.svg' or should the field be icon = activity-web.svg in that case?
We also need to specify the icon format (maybe thinking a bit more to
the css properties and possibly improving them). Something I was
thinking is that the css should be external, only the class attributes
should be required in the svg files... librsvg does not support external
css yet but we can just add the whole css to the svg file after loading.
default_type = _web_olpc._udp
Each activity must have a default type. This must follow the
mDNS specification for serivce types and must be globally unique. This
key is required. It is used as the service type for the mDNS service
when the activity is shared.
Do we actually want to make this required? There are activities that
might not be sharable (terminal for example) or that haven't implement
sharing yet.

Since it's optional might be worth adding that it defaults to no.
