Groupware/sub-project website: Joomla vs groupware soft...? - Joomla! Forum - community, help and support

hi all,

i smile on face, when posts 'can joomla it' in title. yet, time it's me needs advise.

i'm not new joomla, have been building +10 sites, not lot, granted, i'm not pro webdesigner. liked power of joomla, , extensions impressive. yet, time i'm not sure whether joomla can job.

main features i'm after: bit 'sourceforge', when creating project users forum, file storage system, gallery, chat... in other words: users register can create project , doing account linked project includes kind of project profile, basic task manager, basic file repository, images... in sense 'project management' tool, yet user friendly , quite features.
i don't need 'management' software such @ dotproject, there's no need big soft users 'project' managers. it's more end-user, social collaboration thing. simple forum (for can set permissions), message board, file repository system, gallery, calendar, profile... permissions yet user-friendly.

my 'joomla' solution: project fork (the superbundle)
install community builder , sync project fork
i prefer joomla, since allows me develop site , when don't have time, it's not hard less tech minded people take on while. drupal , e.g. typo well, yet demand bit more of developer/maintainter imho...

couple of questions:
- hard install/set up?
- release of joomla 1.6 change site (permissions...)?
- hard e.g. control permissions on each of modules. top-down permissions system stating no template viewable unless project leader decides is...?
- can project profile extended additional fields (e.g. website link...)?
- hard integrate e.g. facebook accounts?
- require superbundle in first place?
- should @ collaboration systems (e.g. bricolage, alfresco...?

wow question , project fork extension since joomla 1.6 still in alpha release expected lot of change come 1.6 better keep in touch updates.
