I tried to do this a while ago and it worked fine.
All I did was to convert the classes.zip into an array with a tiny tool
called file2c or so.
Then I included this file into zextract.c.

After that zextract was changed to read from this array instead of getting
data from the filesystem
by replacing read/write/seek operations.
Also the classpath-type had to be modified somehow.

But this solution was not used in my project, because all the needed
classes had to be in memory
twice: in the zip-archive and loaded into kaffe.
