Temporary customer URL ?

[Eminos]

Hi,

I would like to be able to give my customers temporary URLs for use before their DNSs gets propageted.

Something like:
userdomain.com.customer.myhosting.com
OR
customer.myhosting.net/~userdomain.com

The later one can be achived by a how-to for VHCS, but this doesn't work in ISPCP, I guess due to fcgi and permissions and stuff like that.
( http://vhcs.puuhis.net/wiki/index.php/Te...to_domains )

So, is there a way to implement this into current ispcp ?
Either automatic for all new customers, or (temporarly) manually for customers that wants this.
I really really need this, and this has been discussed before here, in a thread started by me, but back then I couldn't get it to work, and I guess I didn't need it this badly.
Greatful for help.
