I am currently rewriting the package to not be singleton, and the have global, group and private contact lists. I expect a full number release by the end of the month (i need to implement it on one of my sites then so i want it to be as "finished" as possible). As far as vCard import/Export, i'll try. Outlook.csv and yahoo.csv imports/exports will for sure be done by the first release.
Nima, I really think my contacts package is the way for webmail to store contact info. So i'll try to make time to get vCard's working. Would you be willing to email me your webmail tarball? If i see the code it would give me an example of how other packages will need to be able to tie in with contacts. Or, if its not in a state to "share" yet (i.e. it depends on a number of local hacks) once you get it to that level i would appreciate if you could send me the tarball.
