I believe your assessment is correct - that warden is now looking for any use of the prohibited software, even if you are not actually using the software broadcasting ability of that program.

While it could be possible for the HKN team to recompile a new application without those key broadcasting abilities, I have no way to know how likely/unlikely it is that they HKN team would do that just to support WoW multiboxing. My gut feeling is that change is highly unlikely, but that's just my wild-ass-guess.

Instead, I'd suggest that you'd need to look at different software to handle that.

- JoeMultiBoxer (JMB), is made by the same team that did ISBoxer. JMB is more than just ISBoxer without the software broadcasting - it now includes some ability to swap windows based on keystroke or mouseover or to leave windows in place, but to change focus based on keystroke or mouseover. JMB has the same license requirements as ISBoxer ($15/3 months or $50/year)

- WoW Open Box, open source software ([WoW] new opensource compliant wow software (dual-boxing.com) is a free alternative. It handles the renaming and positioning very well. I can't say I've ever tried to do is as a picture-in-picture mode myself though. With this application, you do need to start your clients yourself, then apply the window position to each window - so its 1 or 2 clicks to open each client, then 2 clicks for each client to snap it into place (1 click to select which rule will be applied, then 1 more to apply it).

- Before JMB and WoW Open Box were out I tried a mix of separate software packages to do window positioning, sizing, etc. That worked "OKish". ShiftWindow was probably the key part of trying to roll-your-own, and if you're doing just mouseover focus control that may be all you need. I used it along with some keyboard macros in synergy to change window focus manually. That combination was a bit more troublesome (it worked, but stuttered a lot), but could be workable with some more effort and polish. (I was pinning 5 copies of wow.exe to my taskbar, then switching based on macro'd command to do <windows key> +1 for client 1, <windows key> +2 for client 2, etc) I needed to find a better way to rename windows/change focus based on keystrokes, but I abandoned that approach to focus on getting set up with JMB and WoW Open Box which both seem more promising.
