There were also some concerns about the licensing arrangements & possible 
patent encumerbances for the standards, and the fact that until recently you 
had to pay $9500 to get hold of them..

See the LWN article "InfiniBand: a proprietary standard?" at:

One of the last comments finishes on an upbeat note though, saying:

 Download InfiniBand specification for free

 Looks like the InfiniBand Trade Association reacted. 

 Today, I was able to download the latest version 1.2 of the InfiniBand
 specification here after a simple name and email registration. I did not have
 to sign any licence, nor did the specification itself contain anything beyond
 a copyright statement.

although this doesn't clarify any patent issues..
