And, just something to consider about doing this in reverse:

I'm beginning to see services where I can take a photo of a 2D barcode
with my mobile and MMS it to a service and it returns info to me.

Example: In a server farm, I snap and send barcode to find out who what
sites are on a machine and who "owns" it.

Yes. But that's the wrong question. The correct question is, can the
scanning device scan the bar code on the mobile phone? The answer to
that question is ... in places where they are using visual scanners,
like in much of Europe, it works fine; in the US, the laser scanners
won't work.

The various mobile bar code companies have worked that out nicely. I'd
have to go research to see who is currently in the field.

Yup. Just not really here. Okay, there are some installations on
getting truly paperless airplane tickets: display the ticket data on
the phone and the check-in scanner can read it. This is an environment
in which the scanner is controlled, so it works better. (maybe movie
tickets could do the same, but you'd be behind the competition)

Any which way a picture could get to a phone. MMS is a good answer (be
sure you know how to really send MMS so they get to end users). A web
site could do it (be sure to size the image so that transcoders don't
resize it). An application could do it (but the user would have to get
the application). I wouldn't do email unless you really wanted it on
computers as well, because so few people have email on their phones.
Unless you want to focus on a small set of phones. Consider also IM.
