- While I don't argue that such a sampling/compression/encryption/
- transmission/decryption/decompression/reconstruction could be done virtually
- in real time on a typical phone line with a lot of funding, I will need
- some math and some specifications for devices capable of carrying this out
- reliably on an analog cellular network before I am convinced. I don't have
- bandwidth specs or s/n values for cellular transmissions, so I can't do this
- for myself.

- As for scramblers, I'd like to point out that digital scrambling of phone
- lines (not subscriber lines generally) predates the DES.
