The perl suggestions are the best if you have perl, and it can be
done directly in awk if you have the new awk that can close files. 
I did this sort of thing years ago using:
 awk |sh
where the awk program generates a stream something like:
 cat > filename1 <<\!EOF
 data
 !EOF
 cat > filename2 <<\!EOF
 data
 !EOF
