It might well be that the best thing we can do for the data transfer is to
compress the files. gzip (gnu zip) compresses the Connaly molecule from
635K to 181K.

The text data usually about 8 chars per floating point value. A binary
representation is 4 bytes. That is only a factor of 2. A binary version
of the Connaly molecule is about 235K. (using Inventor on NT)

I agree with Chris and Len - the ASCII and binary formats should be
the same structure.

If lots of data is really a quadmesh, then we can save some data by adding
quadmesh as a primitive. Since the connectivity is implicit, you do not
send it.
