A number of Nikon point and shoot cameras allow zoom while taking movies,
including the S10 Coolpix and Coolpix 8800 which I own.
The 2 GB limit is usually imposed since the file system required to read and
write larger files which are Windows-compliant (called NTFS) takes a lot of
complexity to implement versus the simpler, older FAT file system used in
most cameras. The physical memory of 2 GB may therefore not be the "true"
reason why this file size is limited. The camera could write multiple files
for a movie, breaking the movie into 1 or 2 GB chunks, but they do not seem
to allow this work-around, probably since it also introduces further
complexity.
