I haven't been using SOAP4R yet, but today I looked at bit into SOAP as
such.

It appears that SOAP is getting pretty mainstream. I have seen SOAP4R listed
several places as tool interoperable with whatever other tool, .e.g Apache
Axis and gSOAP.

Here's an article listing SOAP4R in the article "Where Ruby Really
Sparkles", Linux Journal, 2002-09:
http://www.linux-mag.com/2002-09/ruby_04.html
page 1:

I also noticed that the brand new danish / swedish etrade site appear to be
using SOAP internally, since I got a SOAP error :-) Thus SOAP is being
seriously deployed.

So I was wondering if SOAP4R is getting into the standard distribution, now
we have had the YAML thread.
I'm sorry if it already is, I just couldn't find it in my 1.7 pragprog dist.

An issue may be related http servers that would also be required in order to
have a useful server solution.
