300kb extra in the binary and an extra portability headache.

Luatex actually includes the luasocket libraries, so that
would be a better option, but it takes time to write the code
for a http/ftp fetcher to replace curl completely.

If you (or someone else) is interested in writing a replacement
for luat-crl.lua, have a look at:

   http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/

The bare bones usage (for http) is as simple as this:

   local http = require("socket.http")
   local content, responsecode, extra = http.request(arg[1])
   io.write (content)

but in real life, you have to deal with partial content,
errors codes, url escaping, etc. etc.

Best wishes,
Taco
