Beta 2 is looking good. We managed to squeeze that last feature in (enforcing task assignments so only folks assigned to a task can update it) and are in the final weeks of testing now. We have a couple nits beta testers have let us know about and vertical scrolling could still be a little faster, but overall we are very pleased and look forward to even more feedback.
We have identified three installation scenarios to support--
Installation on a Microsoft BPOS or 3rd party hosting solution
Installation on WSS 3.0 or MOSS 2007
Installation on SharePoint Foundation 2010 or SharePoint Server 2010
Because we are making the underlying IntelliGantt Web Part xap file available, you can install it on any SharePoint 2007 or SharePoint 2010 server anywhere! This will make it easy to 'kick the tires' or deploy the IntelliGantt Web Part for your immediate needs. Full instructions for installing the xap file are here.
If you do have administrative access to your SharePoint server, then installing the IntelliGantt Web Part makes sense as it will show up in the web part gallery in the 'Project Management' category.
Here is more information and the download link for the WSS 3.0/MOSS 2007 WSP file.
