Count it more than theory. I have put an open source Linux (OpenWRT) on
an inexpensive Linksys device and used it to configure several Sun Rays
for use over a DSL link. It's a little tricky to setup (at one point, I
had to "debrick" the router!), but it works well once configured. The
Linksys runs dnsmasq which supports the DHCP options needed by the Sun Rays:
# dnsmasq.conf
# Increase the default time-to-live; see
http://www.cse.nd.edu/~striegel/HowTo/WANRay.html
dhcp-option=23,25
# X windows server
dhcp-option=49,<ip_address>
# TFTP server
dhcp-option=66,<ip_address>
Even with this setup working, however, I am still a big advocate for
having the ability to configure these settings in firmware. DHCP
configuration is a great solution for many situations, but fails
miserably when you do not own or control the network in which the Sun
Ray clients are deployed.
Regarding a Soft Ray... almost every potential customer I have talked to
has inquired about this feature. A Soft Ray introduces many issues
(e.g., protecting the client OS) and should not be necessary in the long
run. But for where the market is today, a Soft Ray would be a fabulous
transitional step.

WRT the VPN, it all depends on what your security requirements are.
Some customers are happy with the RC4.
I know the Linksys firmware is open sources. In theory it could he
made to provide the minimum information the SR needs to boot, which
would be to use option 49.
In the future we hope to offer you a way to set this via the firmware.
If you've ever seen a Tadpole Sun Ray, it would be like that.

In other words...
"We provide users with an expensive Cisco so-ho VPN router, which
establishes a VPN-style link to our network, and serves the right
DHCP parameters to the Sun Ray"
(which makes me wonder if there is an equally portable cheaper option
for those of us that got cheap SunRays off eBay and want
tinker-setups to take on-the-go, without having to build a whole
mini-PC running OpenBSD/Linux/etc. and the relevant VPN/DHCP software)
