Hah! It's actually InfiniBand(tm). :-)

FWIW: the name has been OpenFabrics / OFED for a few years now. Not
that I wholly disagree -- we're still stuck with the "openib" module
name in Open MPI because we named it several years ago when it was
called OpenIB -- but I think the "OpenFabrics" name is pretty stable.
OpenIB was an informal name that existed before there was an official
organization behind it. OpenFabrics is the legal entity that was
created to support all things related to this technology, so I don't
think that name will be changing any time soon. Indeed, there's a
*lot* of money put into the marketing and branding with the name
"OpenFabrics".

There hasn't [yet?] been discussion of renaming <infiniband/verbs.h>
(or some of the other IB-centric struct/symbol names), but the whole
package is very definitely marketed as "OpenFabrics verbs", not
"InfiniBand verbs" (although the IB vendors certainly don't correct
this misconception ;-) ).

So I still would like to rename this file before release.

Sun is porting the OpenFabrics verbs to Solaris (to replace their DAPL
stack). There is also talk of porting the verbs API to MS Windows,
although I'm not tracking that effort at all. If all this comes to
fruition, it'll be 3 different platforms that expose the same verbs API.
