Thanks.  I'll update the survey package.  Sudaan does the standard errors on quantiles using Taylor series.  If I can hunt down the formula it uses, could you add that to svyquantile?

svytotal() and svyratio() will do this for totals and ratios if you have a
new enough version. At the moment the easiest way to get row or column
percentages is to think of them them as ratios of means of binary
variables and use svyratio().

Quantiles are more difficult, since neither Taylor series nor jackknife
approaches work.
