Looks like the VUW wireless 802.11 trial is finally allowing better unproxied access to a wider range of stuff on the vuw.ac.nz domain. I'm now able to avoid the 'no, you're not supposed to bill me for library database access' problem I had to go through last year when (seemingly) forced to use the proxy.
It's not totally fixed, yet. It's still locked down unproxied to only a small selection of the vuw.ac.nz domain, and it still doesn't exactly like library databases authenticated through the university's EZproxy server that insist on redirecting to their own hostname instead of browsing via a port on the EZproxy hostname. I probably should bother telling them, as I often use them to download some rather large printable versions. Sometimes it's up to a few megabytes in size.
I guess you can't have everything, but it's at least a bit more useful now.
