I don't think SLIRP was originally for palm pilots, given it was released two years before.

SLIRP was useful when you had a dial up shell, and they wouldn't give you slip or ppp; or it would cost extra. SLIRP is just a userspace program that uses the socket apis, so as long as you could run your own programs and make connections to arbitrary destinations, you could make a dial script to connect your computer up like you had a real ppp account. No incomming connections though (afaik), so you weren't really a peer on the internet, a foreshadowing of ubiquitous NAT/CGNAT perhaps.

That's a mistake indeed; "popularised by" might have been better. Before my beloved Palmpilot arrived one Christmas, I was only using SLIRP to ninja in Netscape and MUD sessions onto a dialup connection which wasn't a very mainstream use.

SLIP not PPP. Those are two very different protocols. Otherwise your comment is fairly accurate. There were dial-in terminals, whether more expensive or not, that could be repurposed for generic Internet access.

I don't recall whether you could technically open listening ports, at least for a single connection, using slirp, but many, if not all systems, limited opening ports under 1024 to superusers, which (would have?) made running servers on standard ports more difficult.

In any case, I'm glad that you pointed out ACM's apparent revisionist history. They should know better.
