is there any app, that could use filr as backend? For example documents 2 free supports dropbox, google docs, skydrive, etc.
If you would like to edit some documents simlpy on-the-fly, you can't do that with Filr. For now, you have to edit the document separately in some app, then "open in" and upload to filr folder.
I don't have to say, that customers, who are already using dropbox/skydrive see this as a sort of absence in usability, when they are considering migration to filr.

I understand, that Filr is there only few weeks, but is there any activity from the Novell side to cooperate with developement teams, who are behind mobile office applications, so we could see in the future also "Filr" option in these office apps?
