I haven't done much with the RsWebParts for since I released the last beta version (sorry if you've sent me email or posted questions in the comments, I've been too busy), but it looks like they are getting some more attention with the release of Reporting Services SP2 beta.
One thing that seems to have gone unnoticed is that the new version of BI Portal has been released [via Duncan and Patrick]. What does BIP have to do with Reporting Services WebParts? Well the BIP viewer can view Reporting Services Reports (and the BIP Viewer is a WebPart). It also has a Report Browser. In fact, the BIP viewer was the inspiration for the RsWebParts and you will even see that I borrowed some of my client side scripting from the BIP viewer.
So now there are 4 Reporting Services WebPart Packages (that I know of) so it will be intereting to see what happens next. I would expect the MS WebParts to come out on top unless they don't provide the functionality that people need. I would really like to continue working on the RsWebParts or at least get it out as an open source community project (especially since GotDotNet is so pathetic, right now the workspaces are down and there is no message explaining why or when things will be back).
What would you suggest? Should I create some kind of open source project for the SharePoint/Reporting Services community to extend? If so, how should I go about this?
