Access Gate 1.1 deployment for multi node Apps Install

Hi,

I read from Steven Chan's blog / some other blog, you need only one Webgate for the whole corporate where as for every E-Business Suite you are installing, you need to have one Access Gate.  Is it true?

If not, can you work with one Access Gate on one server which all the E-Buusiness Servers can use based on the context    Also, how do we do it for multi-node Apps Install with Loadbalancer in the front.    Any one implemented this and have similar situations because I will have to use the load balancer URL for different places.   

Thanks,

Chanth
