S4 coercion
I am extending a DBI connection by
setClass("TSPostgreSQLConnection",
contains=c("PostgreSQLConnection","TSdbOptions"))

afterwards!)
(2)
For the creation of DB connections on every node a function handling
the whole connection is sourced into every node.
This function works perfectly without snowfall.

Rails: Good for everything?
My department is in a battle right now. We have some very por PHP

PHP shines where we go into an existing application, or a new one where
multiple databases or possibly legacy systems are involved. The PHP
guys basically say Rails is good for Web 2.0
