Like many others I have struggled to make DTTG useful. I have successfuly managed to get it to sync with my macbook provided I am on my home WiFi network.
It’s not possible to synchronise using the WiFi at work though, and I think this might be either due to bonjour-blocking (but I don’t think that’s the case) or might have something else to do with the corporate-class WiFi we use. (For example, its neither a class-B nor class-C network, but something in-between).
In my view, advising people to drop firewalls is not good enough. If you must give advice about opening firewalls, please give more details about what ports are really required to be enabled. I am happy to assume the network scope should be “LAN”, as that seems reasonable to me.
Even when it does sync, I find a number of disappointing aspects. For example, if I copy a parent, and one of its sub-groups into the “sync” group at the top level, the sub-group appears in DTTG at the top level, but is absent (not contained within) the parent group. (In other words, some of the group-tagging has been lost or disregarded in the synchronised data). I have experienced many other such disappointments, but will put those aside for now because there is more basiic problem that needs fixing: “basic synching”. Other disappointments include: the limited number of data-types that DTTG can display.
To limit the sync options to bonjour and WiFi is not going to be suitable for all users in all work contexts. Inventing crazy WiFi solutions like “making your Mac project its own mini WiFi network”, is not a solution, its a work-around, and not one that will work in many situations. For example, if you are at work and using work WiFi say for email, you can’t then create a new network just to enable DTTG to synchronise. And some work places I work in (hospitals) consider it rude to set up WiFi nets.
I use omnifocus and that syncs beatifully with moblileMe iDisk. Can we have a range of choices for synchronisation media (not just WiFi), but dropbox, mobileme, bluetooth(!), iPhone USB cable, iTunes … others …? (Just copy ideas that are used by other successful synchronisong applications.)
I shall wait though. I shall wait for updates to DTTG before I can begin using it, and before I can begin trusting it. And I shall be patient, because Devontechnologies are so great, and DevonThink is such a brilliant application which I almost “live inside” every day.
