Hi Clemens, Just a general question how does Caya work internally? Does it use people > files? how does it sync new contacts from there server, does it deletes gone > contacts? How to remove a contact in Caya just over the UI or by deleting > the contact in the FS. > At the moment caya does not support anything of that. A plugin simply connect to the service and returns every contact to caya via multiple BMessages. We hope to develop these functionalities around a set of classes provided by the system. All this sounds like the same problems discussed in the IMAP case. What do > you think about a jabber/icq/... FS? I don't see any good point to make a "jabber-fs"...seems more reasonable for me an api for third party apps as described in previous posts... > A bit off topic: we really should think about such a net service FS > infrastructure with local caching. Another use-case would be picasa/flickr > FS (here an option to flush the download cache would be needed). > Could be useful an addon api around the services kit? Theoretically there's no need to make every "service" to be a userland filesystem...but instead an addon API can provide a "general virtual filesystem creator" where addons puts their data accordingly. What do you think? > Because of the web-sync problem I'm not sure how it is in general possible > to merge contacts. At least it must be done very carefully. > Yes, surely there are some rules to be defined at least. Maybe could be better to provide this functionality only in the "contacts preflet"... Regards
