Hi,

It just struck me that we cannot easily re-use a dissector in the case
where the same protocol is being carried on multiple ports.

For example, SWAT traffic is simply HTTP on port 901.

1. How do we declare that port 901 is HTTP, and should be dissected with
dissect_http?  This could be solved if we have some mechanism involving
preferences where we can bind http to multiple ports. The dissector simply
retrieves a list of ports and adds itself for each.

2. How do we have dissect_http display it in the packet list as SWAT? Since
dissect_http has been hard-coded to refer to its protocol as HTTP, we seem
to be in a bind.

Regards
