At first, I thought that Collanos may serve mainly as a tool for secure peer-to-peer files sharing with an information who changed what etc. It turned out that this is a capable project management application, that has a chat and discussion panel, one can post notes, links add tasks and assign them to team members. Files are stored is a separate directory – after one adds a file to Collanos, it should be opened from the application, not from original folder. This seemed a mistake in design at first, but I appreciated it very quickly. Synchronization of project directory would mean sharing all of its contents and that can be sometimes in the range of many GBs. From time to time some bug appeared here or there, but overall it worked as expected. Peer-to-peer sharing means that both people have to be online for synchronization, but so far situation that I switched computer off before a person could download my changes happened only once and it was during a weekend.
As a side note, it’s nice to see that Eclipse becomes an application platform for quite a number of programs. See for example this list of Eclipse-based software.
