first off it depends on how your server is set up, ie, are all your domains under one master domain like on a cpanel server or are they all individual entities like on an ensim or plesk server. If it is the first, you should be able to access across boundaries, I suspect that if this is the case the techie guys are talking about allowing the domain/IP thru htaccess security.

...but it really depends on how they set it all up for you.
