Greenspan's <a
href="http://www.federalreserve.gov/boarddocs/speeches/2004/20040126/default.htm">latest
speech</a> is a good defense of liberal trade policies.  Unfortunately, he does
not address externalities such as tax-base competition and environmental abuse,
but it's still a good recap of the last 60 years of macroeconomic policies.

Compressed SLIP should <a
href="http://www.ren.nic.in/documents/slip.html">outperform</a> PPP, as PPP has
24 bits of packet overhead that C-SLIP doesn't have (minimal packet format).
The <i>should</i> comes into play as the Van Jacobson and "other" compression
algorithms should be the same compression ratios, and the modems should catch
line noise-created errors. Granted, we're not talking huge differences, but
why pick the slower? ;)
