At 2x,  300kb/sec , the default  cdrecord fs's buffer size  provides 13 
seconds of buffering
that should be enough for  most cases. At higher speed the amount of 
prepocessing
that mkisofs does starts playing a more important role however if you have 
created
a iso image then mkisofs is not a factor.

For illustrative purposes, here is a sample command execution for mkisofs 
piping
an iso 9660 file stream to cdrecord:

mkisofs -R /mount | cdrecord -blank=fast -v fs=4m speed=3 -


That sample command syntax is sufficient for a "normal" cd creation someone
like JKH can probably tell us if it is sufficient for creating a  FreeBSD 
cdrom
"package" distribution  --- that is a resonable large filesystem structure.
