Of the four ice in the 'pioneer' ice set, Meru Mati is quite plain and a bit underwhelming to read. (Others in the set are Gutenberg, Crick, and Turing).
To properly consider its merits, we should look at it on HQ and elsewhere separately:
On HQ: It is a 2 rez, 4 strength, simple EtR (End the Run) barrier. The low rez cost combined with straightforward EtR would qualify it as a good binary 'gearcheck' ice (that forces the runner to find and install a breaker in order to continue). But it also has a favourable comparison of 2 rez to 3 to break using the benchmark fracter Corroder, which would quality it as a pretty good taxing piece of ice.
Other servers: it's a 2 rez, 1 strength, simple EtR barrier. This is still pretty good as gearcheck ice - not quite as cheap as Ice Wall, but reasonably priced for the effect. However, at the lower 1 strength it will be 1 to break with basically any fracter in the game, so it's not at all taxing anymore.
So, it's outstanding value on HQ - especially against criminal runners that love to run all over a weakly defended HQ - and also sometimes useful on other servers. Overall, worth considering in Weyland decks, but the simple economic value it provides is unlikely to justify spending influence bringing it to other factions.
