From personal experience the following work:
FTP: no problem (ipnat has a proxy module to allow non-passive FTP to work)
RealAudio: The UDP stuff wont work but the TCP streams work very nicely. Just
	   get RealPlayer to autodetect the connection type to use and it works
           nicely.
IRC: Not done this on NetBSD but people at work use IRC through the office
     FreeBSD firewall (which is ipfilter/ipnat based like NetBSD)
ICQ: can be persuaded to work but is a bit of a pain.

This is what my office uses to keep track of the Firewall bandwidth usage and
it works really well, again on FreeBSD, but I did test it out on my home 
NetBSD machine and things worked just as well. You will need to do a little 
scripting to make it work but its well documented.
