I contacted vservers. They told me about the planned changes, but admitted they don't have a release date yet. The other solution would be to install PHP myself on my vserver, they said.
I didn't know I was able to install that kind of software but I guess such a task would be almost impossible unless you are some kind of unix/apache expert (unfortunately not my situation). They said they can not offer any kind of support on the installation. I guess for me it's basically a good bye from vservers....
Another solution would be to move to a windows 2000 server, that has a nonbeta release of PHP (I don't want to do that). All the unix servers have the same beta version....
Thats all
