XML-RPC interface issue
(Of the official journals, this looked like the most appropriate place to post this.)
Dreamwidth's XML-RPC interface is returning some results that I would call broken. On both 'login' and 'getfriendgroups' calls, it returns empty lists rather than a list of custom access filter groups (which is what I would expect) or some combination of those and custom reading filter groups (which I would think is inappropriate given that clients are intended for posting and not for reading). The end result is that custom-group entry security is unusable (no groups from which to choose) in any client that implements the XML-RPC protocol as specified in the LiveJournal docs.

The LJ 'friends' concept and the DW 'trust' and 'access' concepts aren't the same. Trying to use the protocol as if they are in some circumstances would be foolish. The solution is to implement new methods, not mis-use the old ones.
I think it might be more accurate at this point to say that you're not willing to extend your LJ client to also support DW - and that's a perfectly reasonable decision for you to make.
