I want to install Matisse on my not Internet connected machine and it seems that the development release files section Matisse archive only works with version 4. Can you put a Matisse for ver 5 there as well?

We will most likely wait for GA to do this, August 6th.

Now that 5.0GA is here I do see the update archive has Matisse. The situation I'm trying to support is we've got licenses for a few seats of MyEclipse and want to do a shared installation. To support this I'll be unpacking the MyEclipse manual install into a shared directory, then each developer can finish up the manual install by attaching to it in Eclipse as a plugin directory. The question then is how to support Matisse - it isn't part of that manual install unpack, so how do I get it into that shared directory so that the others can use it?

To get Matisse for 5.0GA you can download the archived update site and then use the update manager to install both MyEclipse and Matisse from it.
