I'm not sure. I know that Kevin Rosenberg went through
quite an extensive effort a while ago to try to clear
up the license status. In any case, the license issue
is probably only going to be important to you if (a)
you have religious convictions in this area or (b) you
want to bundle ILISP and need to ensure that it's
license is conformant with what you are trying to
create. For Joe Hacker who just wants a tool to help
him develop software with, ILISP is "free" enough.

AFAIK, there is nothing that prevents anyone from
porting LEP (ELI) to any other CL implementation. The
header on most of the ELI files reads:
;; Permission is granted to any individual or
institution to use, copy,
;; modify, and distribute this software, and to
distribute modified
;; versions, provided that this complete copyright and
permission notice is
;; maintained, intact, in all copies and supporting
documentation.

Some of the ELI files contain the GNU copyright notice
in them, so I assume that means all of ELI comes under
the GNU license. However, I'm not a lawyer, so you can
make your own assumptions.

I have used both ELI and ILISP and I prefer ELI
because it is more stable and it supports
multiprocessing (the latter is very hard to do without
once you get used to the advantages it offers).
However, on MS Windows, ACL is the only CL
implementation that ELI has support for.  On Linux,
there has been some work at porting ELI to SBCL and
CMUCL. There was also a fairly extensive port of ELI
done for Scieneer CL.
