The over-the-wire protocol should be the same. I'm not sure about the API,=
=20
but even if it's the same, I'm a bit worried that TI-RPC 2.9 contains=20
bugfixes or features that 2.3 is missing.=20

tirpcsrc_99 used to be available from sun.com, but it isn't anymore. I=20
have a copy at http://www.cendio.se/~astrand/oncrpc/, though.=20

Windows has a lot of different RPC mechanism, but Microsoft does not=20
support the ONC RPC API except that with "Services for UNIX". So if you=20
want to port an application that uses ONC RPC, without using SFU, you'll=20
need an external library. Many commercial ones are available. Several free=
=20
ones are also available, but as far as I understand, none of these are=20
maintained, except http://oncrpc-ms.sourceforge.net/ (which I maintain=20
myself :-).

nfs-utils on Windows doesn't make much sense, but there are other=20
applications that does. unfs3 is one of those. Besides, wouldn't it be=20
nice if developers could use ONC RPC a little bit often, instead of=20
solutions like SOAP ? :-)=20
(http://wanderingbarque.com/nonintersecting/2006/11/15/the-s-stands-for-sim=
ple/=20
is worth reading.)
