The igniterealtime thread has a post containing compatibility test data
between Spark, Pidgin, Psi, and Pandion. Here is my explanation of the
Pandion doesn't support XEP-96, and Pidgin/Gaim is notoriously buggy for file
transfer. The problem with these two has nothing to do with a lack of an
implementation guideline. Someone just needs to step up and fix things.
Spark uses a special variant of XEP-96 that apparently breaks compatibility
with every other client, most likely due to x:data ambiguity. I'd suggest
the Spark guys make an extension that is less prone to misinterpretation.
As far as I can tell, Psi works properly.
Keep in mind that these are not the only clients. Gajim, iChat, and Trillian
are also popular clients that support file transfer, and they may not have
any of the problems described in the igniterealtime thread. The situation
may not be as bad as you think.
