Limitations? Hm... there are not going to be any functional limitations, compared to the version of Roadshow available as part of OS4.
That's good news: I've read something just in the first messages on this thread...
Given the age of the code Roadshow is based upon, you won't see TCP/IP stack features which were added after 1994. This means that features such as path MTU discovery, T/TCP or IPv6 support will not be available. But they are not available in the OS4 version of Roadshow either.
I just have the basics of networking, and I don't know how much MTU path discovery could help in communications, but it's ok; IPv6 would be nice just to be "ready for the future" (if this "future" will come

).
I am determined not to put any DRM or anti-piracy measures into the 68k version, if this is what's mainly on your mind.
The current plan is that you will be able to legally use each copy of Roadshow on up to two computers at the same time, provided you paid for your copy. If you intend to use that copy on more than two computers at the same time, you will have to buy another copy. But (read the bit about DRM and anti-piracy measure above), I will not try to stop you from using your copy on more than two machines at the same time. It's your responsibility to comply with the usage requirements.
Thanks for trusting in the community!

Due to how Roadshow works, it requires Kickstart 2.04 or higher. AmigaOS 1.x is thoroughly unsupported.
The devices, libraries and tools that come with Roadshow will all work on a plain 68000 machine. A special 68020-060 version of "bsdsocket.library", which implements the TCP/IP stack, will be included.
That's about as many "limitations" as I can think of right now.
My A500 is equipped with KS2.04 at the moment, so no problem, and doesn't matter to have it under 1.x.
Not sure how the A500 will be supported, if it doesn't have a dedicated networking interface. You could probably rig something up with "plip.device", "slip.device", "liana.device" or "ppp-serial.device" and the necessary cabling, but it probably won't be quite so much fun 
Yes, I know!

I'm thinking about setting up a net with a serial cable and proper device to another Amiga, and using this last one as gateway.
Hope that a rumored ethernet interface for A500 will come to light as well (otherwise I'll use on my A600 with a proper PCMCIA adapter).
Thanks for the precise info!
