Did you check out the Intel license though?


D. DISTRIBUTION: Distribution of the Redistributables is also subject
to the following limitations: You
(i) shall be solely responsible to your customers for any update or
support obligation or other liability
which may arise from the distribution, (ii) shall not make any
statement that your product is
"certified", or that its performance is guaranteed, by Intel, (iii)
shall not use Intel's name or
trademarks to market your product without written permission, (iv)
shall use a license agreement
that prohibits disassembly and reverse engineering of the
Redistributables, (v) shall indemnify, hold

Are you sure that you can redistribute object code statically linked
against icc runtimes?
