"Webification" is certainly a desirable goal, and HTML cum CGI is a 
foundational aspect of this. Your thoughts vis a vis structure echo mine (I 
was toying with this a few weeks ago, lamenting the fact that I have to do 
CGI via Perl as our current hosting services do not yet support Ruby.

A suggestion: use "standard" language for your passed hash keys, say 
"bgcolor" rather than "H_bcolor". The result would be that anyone reasonably 
skilled in HTML could look at the Ruby code and gain an immediate 
understanding of what is happening.

Ruby is a wonderfully expressive language, a fact that can speed its adoption 
in the mainstream world of web design when compared to Perl and (worse) Java.
Nonetheless, it still provides the power for a strong, experienced programmer 
to create high end web applications while still easing the way for a new, or 
cross discipline, designer to upgrade the functionality of their creations. 
Or, so -I- believe :-)
