Hi,
I had more or less the same problem but it was in our office. I was working on several projects at the same time and , at the time, I was only allocated one static IP.
I had read something about hacking OpenACS as mentioned above to host several OpenACS installs in one static IP. However, I was also experimenting with Apache and PHP.
What I decided to do was to follow the procedure for creating virutal hosts on Apache :

I have been test driving this set up on my development machine for a while and everything seems Ok until recently where I have been experiencing occassional slow downs which I attribute to my hard disk doing a lot of swapping.
Am not certain whether this has anything to do with it or with VMware ,which I am also test driving on my machine, I have yet to determine the cause. Nevertheless, I hope this helps.
Regards,
