As I think qwazix already stated in words I can't find any better, any council ever will be highly supportive when a community group tackles such a project and approaches council for whatever help or support. However please understand that it's not council that starts or executes any projects, nor does council have any power to push developers into a particular direction. RzR already aproached me regarding hosting of such a repo, and I told him right now we're short on disk space on our server but we could *easily* get the CPU, RAM, and disks needed to populate a third blade, and then we have plenty of space for any such harmattan repo. The funds HiFo is stashing are more than sufficient for this.
For the question why it's not already done we probably should open another thread ;-P I bet you have an idea if you didn't live under a stone the last 3 months.

[edit] Of course we also need to consider things like traffic volumes and bandwidth needed, we need to talk to IPHH about that, they offered free hosting for a defined set of resources needed, if we need significantly more than initially estimated we need to ask them if they can do this for us and what they want from us in return for it.

[edit2] You got a very valid and reasonable point in that karma issue for harmattan contributions. We need to rethink this I guess. Anyway tmo posts and tmo thanks are OS-agnostic ;-) So are wiki edits etc.

cheers
