Nope. There are three issues here, really. The second item, "User Mode Access" is probably one or both of two things. A "native" IBA interface (aka Verbs). These are the actual IBA work elements. Things like Subnet Managers need access to this. The other is uDAPL (user Direct Access Programming Library). uDAPL (and kDAPL) are emerging standards for high-speed messaging systems (VIA/IBA/Myrinet type things). uDAPL is likely the protocol most of userspace will want to program to.
