   I am sure this is `under my nose' 
   but I cannot find it, any pointers would be appreciated.

here is an excerpt from the upcoming 1.4.1.96 release NEWS file:

 * New installed module: (database binconv)
 
 This module provides the procedures:
 
  (system-big-endian?) => #t | #f
  (integer->integer-byte-string n size signed? [big-endian? [dest]]) => s
  (integer-byte-string->integer s signed? [big-endian?]) => n

i haven't gotten around to the floating-point variants yet, but the
stubs are there (calling them yields a "not yet implemented" error).  if
you want to play, anoncvs access directions are at:

  http://www.glug.org/alt/

you can use "pre-inst-guile" in the top-level build directory to test
your application w/o installing (presuming you don't need the floating
point variants).
